Trade union Unite is launching a High Court bid to block 113 bin workers losing their jobs in Birmingham.

The case is being brought against the background of an ongoing strike over proposals for reorganising the city's waste collection services.

Unite was due to start its legal challenge in London on Thursday, but the hearing was re-fixed for Monday next week because of time constraints on it taking place this week.

The union is seeking an interim injunction restraining Birmingham City Council' from dismissing grade three "leading hands", referred to in court as middle grade waste collection supervisors, pending a full legal challenge over the legality of the council's actions.

The redundancy notices were due to take effect on October 1, but the council undertook to extend the deadline by three days to October 4 in view of the delayed court hearing.

The court had heard the bin workers were under serious time pressures to decide whether, if the legal challenge fails, to take lower grade jobs, seek other grade three employment or apply for employment outside the local authority.

The union is arguing the council's actions are unlawful and breach an agreement reached through Acas.

The bin strike started this summer, and a ballot for further action is expected to be completed on September 18.
